A series of faults caused by insufficient repair of synchronization gears 1. Case background A customer had a self-repaired Roots blower that experienced abnormal vibration and sound during startup and operation, and was forced to shut down, which affected production.

In-depth disassembly and failure analysis Cause of failure: After disassembly, it was found that the root cause of the equipment failure was that the customer's previous repair process for the synchronization gear was not in place or the repair plan was technically undesirable. Evidence of failure: while dismantling
